ExpoDisc v3 Professional White Balance Filter (77mm)

ExpoDisc v3 Professional White Balance Filter (77mm)
- ASSEMBLED AND TESTED IN USA: We care about our products - we assemble, test and certify every ExpoDisc in California on our transmission spectrophotometer.
- EASIER-TO-USE THAN A GRAY CARD: Simply place the ExpoDisc v3 in front of your lens and capture the incident light while setting your white balance.
- QUICKLY SET WHITE BALANCE: Save time by setting your photo or video white balance in-camera (no software required), or capture a gray reference image to use with your preferred image editing software when processing your RAW files in post production. In most cameras you can set a white balance in 15-20 seconds.
- NEW WIDE SPECTRUM WHITE BALANCE: The ExpoDisc v3 enables precise custom white balance adjustment across the visible spectrum (380nm to 700nm) and extends to the infrared spectrum (700nm to 1600nm). With a light transmission delta of only 0.9% from 380nm to 700nm, the ExpoDisc v3 ensures accurate color reproduction in the visible range.
- THINNER AND LIGHTER: ExpoDisc v3 is wafer thin (9mm), which is about 1/2 the thickness as the ExpoDisc 2.0. This makes ExpoDisc v3 easier to hold over your lens, and more comfortable to slip into your pocket.
- NEW BAYONET MOUNT: The new ExpoDisc v3 introduces a redesigned mount, catering to users who prefer attaching the ExpoDisc directly to their lens during white balance adjustment.
- CALIBRATED LIGHT TRANSMISSION: The new ExpoDisc v3 is calibrated to be inline with ANSI standards for digital light meters, ensuring approximately 14% light transmission.
- IMPROVED EXPOSURE ACCURACY: With this calibration, the ExpoDisc v3 offers a notable improvement of approximately 1/3 to 1/2 f/stop when using it for exposure metering on digital cameras.
- EASY SETUP: With the inclusion of a step ring, attaching the ExpoDisc v3 to your lens becomes a breeze. Simply thread the step ring onto your lens and effortlessly mount the ExpoDisc v3 onto the step ring whenever you set a white balance.
- INFRARED (IR) WHITE BALANCE: ExpoDisc v3 maintains excellent light transmission with a delta of just 1.1% from 700nm to 1600nm allowing for consistent white balance in infrared wavelengths.
